Cisco Unified Communications Manager SNMP Trap Agent denial of service
| cucm-snmp-dos (42420) |  Low Risk |
Description:
Cisco Unified Communications Manager (CUCM) is vulnerable to a denial of service, caused by improper handling of packets by the SNMP Trap Agent service. By sending specially-crafted UDP packets to port 61441, a remote attacker could exploit this vulnerability to cause the service to restart and core dump, resulting in a denial of service.
Platforms Affected:
- Cisco, Unified Communications Manager 4.1
- Cisco, Unified Communications Manager 4.2
- Cisco, Unified Communications Manager 4.3
- Cisco, Unified Communications Manager 5.0
- Cisco, Unified Communications Manager 5.1
- Cisco, Unified Communications Manager 5.1(1)
- Cisco, Unified Communications Manager 5.1(2)
- Cisco, Unified Communications Manager 5.1(2b)
- Cisco, Unified Communications Manager 6.0
- Cisco, Unified Communications Manager 6.0(1a)
- Cisco, Unified Communications Manager 6.1(1a)
